This low level, split bridge takes the South Fraser Perimeter Road over Center Creek. It was designed and built to protect wetland areas and to allow the natural sunlight to filter down to the wetlands below, helping to support wildlife and vegetation.
This project was built using a “top down” construction method; meaning that the structure itself was used to support construction loads with no heavy equipment on the ground. The work involved driving 610mm diameter pipe piles to depths in excess of 30M, filling the piles with concrete and reinforcing steel, installing prefabricated structural steel pile caps and girders and placing of precast concrete deck panels for the finished roadway. Work on both parallel structures was carried out from the north structure only. The work also included construction of abutments and end fills incorporating MSE retaining walls. Due to the environmental red zone classification of the site, all clearing activities were done by hand work using small tools and light equipment only.
